Description

Hygiene management device for entrance hall and control method of the same}

The present invention relates to a phase management device for an entrance and a control method thereof.

In general, in order to enter the indoor space from the outside while separating the outside and the inside space, it is necessary to pass through the entrance. For example, in the case of a house, an entrance is provided as an entrance, so a person must pass through the entrance to enter the house.

Recently, when the external air quality is getting worse, such as yellow dust or fine dust, when entering the indoor space from the outside, the indoor space may be polluted.

In a dense environment such as an apartment, there is a problem of passing on the pollution to the surrounding people when the work of removing pollution outside the door is carried out. Therefore, it is necessary to decontaminate the entrants from the entrance such as the entrance before entering the room.

Techniques for preventing the transfer of pollutants to indoor spaces are disclosed.

In Korea Patent Laid-Open Patent No. 10-2009-0040630 (Prior Document 1), an air shower device for a home entrance has been proposed. Prior Document 1 removes contamination such as dust on the clothes of the entrants by performing an air shower for the entrants.

However, since the air applied to the occupant flows from the top to the bottom, the air is mainly applied to the occupant's head and upper body, so there is a problem that the contamination of the lower body and shoes cannot be properly removed. In addition, there is a problem in that contaminants such as dust remain on the floor of the entrance because the intake port through which air is sucked in the entrance is on the side of the entrance space.

Korean Patent Application Laid-Open No. 10-2020-0117286 (Prior Document 2) discloses a door air shower system. In Prior Document 2, in addition to an air shower, a photocatalytic lamp is installed on the ceiling to remove contamination such as dust on the clothes of the occupants and to purify harmful substances such as viruses.

However, in Prior Document 2, there is a problem in that contaminants such as dust remain on the floor of the entrance hall, and since the photocatalytic lamp irradiates light from the ceiling, there is a problem that the contamination on the lower body and shoes of the entrant cannot be properly removed.

Korean Patent Application Laid-Open No. 10-2020-0046715 (Prior Document 3) discloses a lighting-integrated air cleaning system for an access space and a control method thereof. Prior Document 3 performs decontamination of entrants in an entrance space such as a hallway by integrating a lighting fixture and an air cleaning device.

However, Prior Document 3 also has a problem in that the structure for simply spraying air from the top to the bottom is integrated into the lighting fixture, and the contamination in the entrance space is not properly removed because the suction port is on the side of the entrance space.

Korean Patent Application Laid-Open No. 10-2019-0055303 (Prior Document 4) discloses a front door integrated air shower device. In Prior Document 4, a shower booth having a shower space was installed separately so that an occupant could remove contaminants from the shower booth.

However, since the shower booth of Prior Document 4 is separately partitioned in the space within the entrance hall, the space occupied by the entire device in the entrance hall increases, thereby reducing effectiveness. There is a problem with falling.

In addition, in the preceding documents 1 to 4, there is a problem in that outdoor pollutants are introduced into the entrance through the door in the process of opening and closing the entrance door, thereby contaminating the interior space of the entrance.

The duct 400 may serve to move the airflow formed in the fan assembly 300 to a relatively upper portion of the doorway 10 . The duct 400 may include a first duct 410 and a second duct 420 .

The first duct 410 may extend along the sidewall of the entrance 10 . The first inlet 412 of the first duct 410 is connected to the outlet of the fan housing 310 of the fan assembly 300 so that air flows through the outlet of the fan housing 310 through the first of the first duct 410 . may be delivered to the inlet 412 .

The first duct 410 may have a branch flow path (not shown) capable of supplying air to the function module 350 . There is a separate damper inside the branch flow path and the first duct 410 to control the flow of air through the inside.

The second duct 420 may be located above the entrance 10 . The second duct 420 may supply air to the air injector 500 to be described below while the air passing through the first duct 410 flows. The second duct 420 may have a first outlet 422 and a second outlet 424 .

The first outlet 422 may be in a relatively upstream portion of the second duct 420 with respect to the moving direction of air in the second duct 420 , and the second outlet 424 is greater than the first outlet 422 . It may be relatively downstream. As can be seen in FIG. 3 , the first outlet 422 is closer to the first duct 410 than the second outlet 424 .

The air injector 500 may be connected to the second duct 420 above the entrance 10 . The air injector 500 may inject the air delivered through the duct 400 into the space 12 of the entrance 10 .

The air injector 500 may inject the air delivered through the first outlet 422 and the second outlet 424 of the second duct 420 into the space 12 , respectively. In the air injector 500 , the delivered air can be set and changed in air volume, wind speed, and direction.

The air injector 500 may have an injection port (not shown) through which air is discharged. The injection hole may be formed at a position corresponding to the first outlet 422 and the second outlet 424 of the second duct 420 in this embodiment. The injection port may be opened to the bottom of the air injector 500 .

A corrugated pipe 556 may be installed at a portion where the second duct 420 and the air injector 500 are connected to prevent air leakage even when the air injector 500 moves.

Since the corrugated pipe 556 is expandable and contractible, the connection state between the second duct 420 and the air injector 500 can be maintained even when the air injector 500 moves with respect to the duct 400 . The corrugated pipe 556 may connect the second duct 420 and the air injector 500 at the first outlet 422 and the second outlet 424 of the second duct 420 , respectively.

The air injector 500 may include a lifting assembly 520 . The elevating assembly 520 may include a first elevating mechanism 521 and a second elevating mechanism 521 ′. The lifting assembly 520 may be driven by a controller 900 to be described below.

The first and second lifting mechanisms 521 and 521 ′ are for tilting the air injector 500 by lifting and lowering both edges of the air injector 500 .

The first lifting mechanism 521 and the second lifting mechanism 521' are installed on the opposite edge sides of the air injector 500, and a specific part of the air injector 500 is moved by these lifting mechanisms 521 and 521'. By descending, the air injector 500 may be tilted.

Accordingly, it is possible to adjust the direction in which the air is sprayed by adjusting the direction (angle) in which the bottom surface of the air injector 500 faces. The driving force for the operation of the first and second lifting mechanisms 521 and 521 ′ may be provided by the respective lifting motors 524 .

Some of the components of the first and second lifting mechanisms 521 and 521 ′ may be installed in the upper portion of the second duct 420 or the entrance space 12 , and the rest may be installed in the air injector 500 . The direction in which the bottom surface of the air injector 500 faces may be adjusted by lifting a specific part of the air injector 500 by the lifting mechanisms 521 and 521 ′.

The first and second lifting mechanisms 521 and 521 ′ may be replaced with other components that perform the same function. In the present invention, any configuration is applicable as long as the air injector 500 can be tilted in a specific direction.

A plurality of vanes 560 and 560' are provided between the first outlet 422 of the duct 400 and one injection port of the air injector 500 and between the second outlet 424 and the other injection port of the air injector 500, respectively. can be installed.

A vane rotation center member 558 may be installed at the first outlet 422 and the second outlet 424 of the second duct 400 , respectively. A plurality of vanes 560 and 560 ′ may be rotatably installed at a predetermined angle on the vane rotation center member 558 .

The vanes 560 and 560 ′ may set the direction of the air discharged through the injection hole of the air injector 500 . A plurality of vanes 560 and 560' may be disposed at predetermined intervals.

The vanes 560 and 560' may serve to set the direction of the air discharged through the injection hole. As shown in FIG. 8 , the vanes 560 and 560 ′ may be connected such that an upstream portion 561 and a downstream portion 561 ′, which are plates having a predetermined shape, have a predetermined angle. The upstream portion 561 and the downstream portion 561 ′ are connected by a connecting curved portion 561 ″ having a predetermined radius of curvature.

At least a portion of the upstream portion of the vanes 560 and 560 ′ may be located in the second duct 420 . The downstream portions of the vanes 560 , 560 ′ may be located primarily within the air injector 500 .

A larger portion of the vanes 560 and 560 ′ may be positioned inside the second duct 420 as the air travels in the second duct 420 . In other words, the height of the vanes 560 and 560 ′ in the second duct 420 may be at a higher position in the moving direction of the air. In addition, the vane 560 at the second outlet 424 may be at a higher position than the vane 560 ′ at the first outlet 422 .

Such a configuration can also be seen in FIG. 3 . This is to allow the air flowing in the second duct 420 to flow uniformly through the entire area of the second outlet 424 .

The length of the vanes 560 and 560 ′ may be relatively longer when positioned at the first outlet 422 than at the second outlet 424 . This is to allow air to flow well through the injection hole without wasted air going toward the end of the second duct 420 .

The vanes 560 and 560 ′ may guide air to the lower region of the air injector 500 . The direction of guiding the air may vary depending on the state in which the vanes 560 and 560 ′ are rotated with respect to the vane rotation center member 558 .

There may be a vane driving member 562 to adjust the installation state of the vanes 560 and 560'. The vane driving member 562 may be connected to each of the vanes 560 and 560 ′ like the vane rotation center member 558 .

The vane driving member 562 may be connected to the vanes 560 and 560 ′ and relative rotation at a position where the vane rotation center member 558 is moved toward the injection port in the portion connected to the vanes 560 and 560 ′. Two vane driving members 562 may be used, one on both sides of the vanes 560 and 560'. Alternatively, only one vane driving member 562 may be used.

Each vane motor 570 for driving the vanes 560 and 560' may be installed. A drive link 574 may be connected to the vane motor 570 . The driving link 574 may be driven by the operation of the vane motor 570 .

The driving link 574 may be connected to the vane driving member 562 so that the vane driving member 562 may be driven according to the driving of the driving link 574 .

Meanwhile, the hygiene management apparatus 1000 may include first and second sensing units 354 and 356 . The first detection unit 354 may detect the opening/closing of the door 14 , and the second detection unit 354 may detect the presence of a user at a set position in the space 12 of the entrance 10 . can Preferably, the presence or absence of the user on the footrest 100 may be detected.

The first detection unit 354 may be installed on the door 14 and may be implemented as, for example, a reed switch, a push-pull switch, or the like.

The second sensing unit 356 may be installed on the front side of the function module 350 . However, the installation position of the second sensing unit 356 is irrelevant as long as it can detect the user on the footrest 100 . The second sensing unit 356 may be implemented as, for example, an infrared sensor, an ultrasonic sensor, a laser distance sensor, or the like.

Alternatively, the second sensing unit 356 may be installed on the footrest 100 to detect whether the user has stood on the footrest 100 . To this end, the second sensing unit 356 may be implemented as a weight sensor, a piezoelectric sensor, or the like.

The first and second sensing units 354 and 356 may transmit the sensed result to the control unit 900 to be described below, respectively.

10 is a block diagram of components connected to a control unit for controlling the present hygiene management device, and FIGS. 10 to 14 are flowcharts illustrating a control method of the hygiene management device according to embodiments of the present invention.

The operation of the present hygiene management device 1000 according to the opening and closing of the door 14 will be described with reference to FIGS. 10 and 11 .

The hygiene management device 1000 of the present invention may initially maintain a standby state in a state installed in the space 12 of the entrance 10 (S101). In the standby state, the air injector 500 may be set to face a set initial direction, preferably, toward the center direction of the space 12 of the entrance 10 . And in the standby state, the air is not injected from the air injector (500).

When the door 14 is opened during the standby state, the first detection unit 354 may detect the opening of the door 14 ( S103 ). The sensed result may be transmitted to the controller 900 .

Accordingly, the control unit 900 may drive the lifting assembly 520 to tilt the air injector 500 so that the bottom surface of the air injector 500 faces toward the door 14 ( S105 ). That is, the direction in which air is sprayed from the air injector 500 may be the door 14 direction.

And the control unit 900 may drive the fan assembly 300 so that air is injected from the air injector 500 (S107).

This is to inject air in the direction of the door 14 from the air injector 500 to prevent air from entering the entrance space 12 from the outside through the open door 14 . At this time, in a state in which the air injector 500 is tilted, the fan assembly 300 may be driven to inject air at a relatively higher wind pressure.

9 shows an operation example in which the air injector 500 is tilted in the direction of the door 14 so that the bottom surface of the air injector 500 is inclined in the direction of the door 14 .

9 (a) shows that the bottom surface of the air injector 500 is directed downward, and (b) shows that the bottom surface is directed to the right. For example, in (b) of FIG. 9, the height of the air injector 500 on the side where the first lifting mechanism 521 is located is lowered, and the air injector 500 on the side where the second lifting mechanism 521' is relatively lowered. has increased in height.

In this way, the air injector 500 is able to inject the air obliquely toward the door 14 direction. Opposite this operation, the air injector 500 can be returned to the set initial position in the tilted state.

Here, the tilting step (S105) and the air spraying step (S107) of the air injector 500 may be performed simultaneously or with a set time difference. Alternatively, in another embodiment, the air injection step may be performed before the tilting step.

Thereafter, when the door 14 is closed, the first detection unit 354 may detect the closing of the door 14 ( S109 ). The sensed result may be transmitted to the controller 900 .

Accordingly, the control unit 900 may drive the lifting assembly 520 so that the air injector 500 tilted in the direction of the door 14 returns to its initial position (S111). In the initial position, the direction in which the air is sprayed from the air injector 500 may be the central direction of the space 12 of the entrance 10 .

When the air injector 500 is tilted to the initial position, it may be determined whether or not to terminate the air injection according to the presence of a user in the space 12 of the entrance 10 .

An operation of the present hygiene management apparatus 1000 according to a case in which the user climbs on the footrest 100 will be described with reference to FIGS. 10 and 12 .

The hygiene management device 1000 maintains a standby state (S201), and when the user climbs on the scaffold 100, the second sensing unit 356 may detect the user on the scaffold 100 (S203). The sensed result may be transmitted to the controller 900 .

Accordingly, the control unit 900 may drive the fan assembly 300 so that air is sprayed in the direction of the user from the air injector 500 (S205). This is to remove contaminants from the user's body or clothing through air jetting.

Air injection may be performed for a set time, and when the set time elapses (S207), the control unit 900 may stop the fan assembly 300 to end the air injection (S209).
